libharu not finding libpng dependency

[philip@…]

Summary: libharu did not find the libpng dependency, so failed. After installing libpng it worked.

Is your libpng port installed with +universal as well: port installed libpng? Though I see libpng isn't listed as a dependency of libharu, so either it should be or it shouldn't be trying to use it...

[philip@…]

It is. But just to be clear, at the time of installing libharu (initially), libpng wasn't installed at all.

libpng added to dependencies.
